Introduction

In this dashboard we will explore a very dull and over-used data set called iris. It’s okay that it’s boring; it allows us to focus on learning a new tool, which is flexdashboard! Below you see some eye-catching summary stats. Typically, you’ll want these to be interesting, high-level summaries!

Distribution of Petal Length by Species

Relationship between Sepal Width, Length

Relationship between Petal Width, Length

Classification tree

Our primary goal is to predict the species based on physical characteristics. We’ve fit a classification tree using the rpart algorithm. Trees are kind of nice for interpretability, but it isn’t the strongest prediction tool.
